commands: make "hg import" use dirstateguard only for --no-commit Previous patch made dirstate changes in a transaction scope "all or nothing". Therefore, 'dirstateguard' is meaningless, if its scope is as same as one of the related transaction. Before this patch, "hg import" uses 'dirstateguard' always, but transaction is also started if '--no-commit' isn't specified. To avoid redundancy, this patch makes "hg import" use dirstateguard only if transaction isn't started (= '--no-commit' is specified). In this patch, 'if dsguard' can be examined safely, because 'dsguard' is initialized (with None) before outermost 'try'.
